There is a very strong bond between mother and calf and they spend a lot of time in close physical contact. Humpback whales are known for their magical songs, which travel for great distances through the world's oceans. These sequences of moans, howls, cries, and other noises are quite complex and often continue for hours on end.
Reef scene with hard and soft corals and feather stars, Ha'apai, tonga
Coral reefs are the most diverse and beautiful of all marine habitats. Large wave resistant structures have accumulated from the slow growth of corals. The development of these structures is aided by algae that are symbiotic with reef-building corals. Coralline algae, sponges, and other organisms, combined with a number of cementation processes also contribute to reef growth.
Clownfish perform an elaborate dance with an anemone before taking up residence, gently touching its tentacles with different parts of their bodies until they are acclimated to their host. A layer of mucus on the clownfish's skin makes it immune to the fish-eating anemone's lethal sting. In exchange for safety from predators and food scraps, the clownfish drives off intruders and preens its host, removing parasites.
Vanuatu's flora is thought to resemble that of the Solomon Islands and Fiji, and the reef ecosystems support a number of Australian species.

The Coastline of the Coromandel Penninsula, New Zealand
The peninsula is steep and hilly, and is largely covered in temperate rain forest. Its rugged nature means that much of it is relatively isolated, and the interior and northern tip are both largely undeveloped and sparsely inhabited. A forest park covers much of the peninsula's interior.
New Zealand stingrays.
Poor Knights Marine Reserve, Northland, New Zealand. Stingrays congregate in the many archways at the Poor Knights Islands. This behaviour is believed to be associated with mating.
Traditional Tongan dugout canoe.
Foa Island, Ha’apai, Tonga. Traditonal Tongan dugout canoe still used for inshore reef fishing.

Why Value the Oceans?

Oceans cover almost three-quarters of the planet, yet we are just beginning to discover the extent of the resources, both biotic and abiotic, that lie beneath their surfaces.

We are also just beginning to understand the complexity of the interactions that tie oceans to the rest of Earth’s systems including the coastal biome, where vital ecosystem services are most vulnerable.

There is a growing demand from decision makers to better manage human activities and their impact on ecosystems and their services and to better understand and acknowledge the dependence of human well being on healthy ecosystems independent of human needs.
